Long-Term Optical Monitoring of Eta Carinae. Multiband light curves for a complete orbital period
E. Fernandez-Lajus, C. Farina, A. F. Torres +8
The periodicity of 5.5 years for some observational events occurring in Eta Carinae manifests itself across a large wavelength range and has been associated with its binary nature.…
The very massive X-ray bright binary system Wack 2134 (= WR 21a)
V. S. Niemela, R. C. Gamen, R. H. Barba +5
From the radial velocities of the N IV 4058 and He II 4686 emission lines, and the N V 4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-r…
Discovery of a [WO] central star in the planetary nebula Th 2-A
W. A. Weidmann, R. Gamen, R. J. Diaz +1
% context About 2500 planetary nebulae are known in our Galaxy but only 224 have central stars with reported spectral types in the Strasbourg-ESO Catalogue of Galactic Planetary Ne…
The periodicity of the eta Carinae events
A. Damineli, M. F. Corcoran, D. J. Hillier +14
Extensive spectral observations of eta Carinae over the last cycle, and particularly around the 2003.5 low excitation event, have been obtained. The variability of both narrow and…
The stellar upper mass limit in the solar neighborhood
J. Maíz Apellániz, Nolan R. Walborn, N. I. Morrell +4
We are using HST GO programs 10205, 10602, and 10898 to test the stellar upper mass limit in the solar vicinity by attempting to detect optical close companions, thus lowering the…
Pismis 24-1: The Stellar Upper Mass Limit Preserved
J. Maíz Apellániz, Nolan R. Walborn, N. I. Morrell +2
Is there a stellar upper mass limit? Recent statistical work seems to indicate that there is and that it is in the vicinity of 150 solar masses. In this paper we use HST and ground…
